Bwahahahaha! It doesn’t have to be a manly laugh! Most endearing is just the way you do. I used to know a guy back in my 20s that when he laughs, he likes to tickle somebody as well (usually happens when I’m next to him). I think he’s a bit shy about his laugh because it didn’t sound manly enough. Gosh, who cares! Laugh like a hyena! I wouldn’t care!
